The Kamov Ka-137, previously designated MBVK-137, is an unmanned multipurpose helicopter designed for many roles, including reconnaissance, patrol, police and ecology, emergency, and data transmitting. Three versions of the Ka-137 were made — one ship-based, one automobile-based, and another carried by the Ka-32 helicopter. The aircraft uses a piston engine, driving a coaxial-rotor system and features a tailless, sphere-shaped fuselage with four-leg leaf-spring landing gear. Sensors and other equipment are located in a special equipment compartment.
